This is a problem that looks like it's common but I haven't found a solution yet. Basically, when playing FTB (playing Ultimate right now, this also used to happen with Mindcrack but it's much more common now), after a short while I'll start to get massive freezing. Like, the game will freeze for 10 seconds a couple of times, and then it will be fine and then it will freeze again.

Since everytime this happen Windows in general freezed at the same time, I fired up Resource Monitor and discovered that FTB was using 1.5 - 2 GB, using up all my free RAM and causing loads of page faulting. I've tried the "-XX:permSize=128m" thing, and my max memory is set at 768 MB. I've tried installing Optifine. None of these things helped. What can I do? The game is pretty much unplayable like this.

Specs:
Windows 7 64 bit, Java 7 64 bit
CPU: Intel Core i5 2500K
GPU: Nvidia GeForce GTX 460 SE
4 GB RAM

Please post your entire client side console log on pastebin.com and link your paste URL here. This is the other window that is opened by the FTB launcher. Please post any and all other logs you can provide to pastebin.com and link those as well. Logs are much easier to read when uploaded to pastebin. To prevent future issues, such as pastebin flagging your log as spam and deleting it, it is simplest to create an account on pastebin.com and use that account to upload your logs.
